I have changed this to use ksm_disable() instead [1], which then also removes vm_flags_t usage from there. Please take a look at it whenever you can. Since it also removes the EXPORT of ksm_madvise(), I think we will anyways need an Acked-by there. (note that: looking at those changes, it seems like it should go via powerpc tree) [1]: https://lore.kernel.org/linuxppc-dev/0500fbfbb98776091c89584155368610095b4dd5.1794537345.git.ritesh.list@gmail.com/ -ritesh
